This is an instance where groff 1.23.0 might be a convenience rather
than a horror show.

commit 2a99e14dc1ffd73c48457709deb8a6115b955955

    [ms]: Apply depth-specific indents to TOC entries.
    
    * tmac/s.tmac (XH-UPDATE-TOC): Modify Keith Marshall's new XN/XH feature
      to indent TOC entries by section heading depth.  The increment is 2
      ens per depth level.

Also, for your enjoyment (I hope), I'm attach a document groff started
shipping (again) in 1.23.0.  You might find it both familiar and
strange.  This edition of it is from bleeding-edge Git.

I would very much appreciate your feedback on it.

Regards,
Branden
